Impact Of A Jet .
The apparatus consists of a cylindrical clear acrylic fabrication
with provision for levelling. Water is fed through a nozzle and
discharged vertically to strike a target carried on a stem which extends
through the cover.
A weight carrier is mounted on the upper end of the stem. The dead weight of the moving parts is counter-balanced by a compression spring. The vertical force exerted on the target plate is measured by adding the weights supplied to the weight pan until the mark on the weight pan corresponds with the level gauge. A total of four targets are provided: a flat plate, a 120Ã‚° cone and a hemispherical cup.
